Question about brew...

Boomer said:

I've looked, but I can't find anything while searching about this, so forgive me if it's been posted before...

I think I may have measured wrong. I have a 6.5 gal carboy but it's still coming out of the blow off pretty heavily. I had to switch to a blow off this morning because the airlock was full of foam. I thought it was just the kit/yeast but I'm thinking I may have added too much water to the carboy. Assuming I put too much water (I did a partial boil) I'm guessing I don't have enough headspace. Seems like a fairly easy fix for my next batch, and a lesson learned on this, my first ever brew. Could this change the outcome? Should I expect a weaker brew both in flavor and/or alcohol content? My initial hydrometer reading prior to pitching yeast was 1.050.

Thanks in advance.

What I do is I have used a magic marker to show 5 USG (19L) and 20L, as I only have the 6USG (5 Gallons imperial) carboys. I only fill them to 19 or 20 litres, just so I have the headroom. If you added water, you have changed your OG by a few points. The gravity change depends on how much you had originally, and how much water you added. As for your last question, yes, your brew will be weaker in both taste and alcohol, but probably not by much.

The good news is that you've already learned from your mistake. Which puts you ahead of me the first time I fermented anything

One option you might want to consider: do a search here for glass etching... permanent marker is nowhere near as permanent as we'd all like it to be on glass

I filled my carboys using a 2 quart measuring cup, and made a mark there, so in the end I had the carboy marked every half gallon. I marked each gallon with its number next to its line, I used my wifes nail polish to mark it, and havent had an issue with a line coming off and its been about a year
